Systems and methods for a SPDT switch or SPMT switch with transformer

A SPDT (single pole double throw) or SPMT (single pole multi-throw) switch system, comprising:

• a transformer having a primary winding and a secondary winding, wherein the primary winding and the secondary winding each have respective first and second ends, wherein the first end of the secondary winding is connected to a single pole port, wherein the first end of the primary winding is connected to a first differential port, wherein the second end of the primary winding is connected to a second differential port, wherein the first and second differential ports collectively form a first throw port;
• a first switch having a first end and a second end, wherein the first end is connected to ground;
• and
• a second switch having a first end and a second end, wherein the second end of the secondary winding is connected to both the second end of the first switch and the first end of the second switch, wherein the second end of the second switch is connected to a second throw port,
• wherein the first switch controls, at least in part, a first communication path between the single pole port and the first throw port, and
• wherein the second switch controls, at least in part, a second communication path between the second throw port and the single pole port.
